"Colibri" by Katia is crafted in Spain of 51% cotton, 45% acrylic & 4% nylon. It is one of the most interesting boucle yarns we've seen in a long time, and is a marvelous addition to your wardrobe. Its mini-looped construction changes from a thicker, colorful, nubby strand to a thin thread-like boucle in neutral tones and back again throughout each ball. The end result is great color and texture combos for your spring/summer knitting & crochet projects.
